Answer 1

Step-by-step explanation:

Radius of the circular wire=0.42m

Circumference of the circle=2πr

=>2×(22/7)×0.42

=>(2×22×42)/(7×100)

=>2×22×6/100

=>264/100

=>2.64 m

Now it is bend into square the total length is used to make that

=>Circumference of the circle =Perimeter of the square

=>4a=2.64

=>a=2.64/4

=>a=0.66

The side of the square=0.66m

Answer 2

Answer:

hey mate!

here is your answer..

radius of circle=42 cm

area of circle=pi r^2

=22/7.42.42

5544 cm^

circumference of the circle =2. pi.

=2.22/7.42

=264 cm

perimeter of square = circumference of the circle.

4. side=264 cm

side=264/4=66 cm

side of square=66 cm

area of square is 4356 cm^

area of circle:area of square=5544/4356=14/11

therefore area of circle:area of square=14/11
